Earthquake-Ready Water Heaters
Short answer: California requires water heaters to be braced or strapped so they can't tip. Two straps around the tank, anchored to the wall studs, plus flexible gas and water connectors, keep lines from breaking when the ground shakes.
Request a plumberWhy it matters
A tipped tank can break the gas line and start a fire, or flood the garage.
Straps
Two metal straps around the upper and lower parts of the tank, anchored into studs.
Flexible connectors
Flexible gas and water connectors allow some movement.
Older installs
Plumber's tape or a single strap may not be enough.
After a quake
Check the tank, straps and connectors; smell for gas.
Gas shut-off
Know where your gas meter valve is and keep a wrench nearby. Only close it if you smell or hear a leak.
Seismic gas valves
Some homes add an automatic shut-off valve.
New tanks
A plumber installs straps and connectors with every replacement.
Water supply
A strapped tank holds emergency water after a quake.
Inspections
Home sales in California usually include water heater strapping checks.
Garage layout
Tanks in garages often sit beside stored boxes and cars. Keep the area around the heater clear so a plumber can reach the straps, valves and venting, and so nothing falls against it in a quake.
Raised platforms
Gas heaters in garages are usually raised off the floor. The platform itself should be solid enough to hold a full tank, which weighs several hundred pounds.
